Solution Overview

Problem

Existing separator systems for air inlet flows face challenges in maintenance and mounting due to compact construction and limited accessibility, particularly in ship ventilation systems, where external installation is necessary but visually unappealing and space-consuming, and internal installation requires downstream access which is not always feasible.

Innovation Solution

A modular separator system with separate parts that can be progressively mounted and demounted through the air inlet channel opening, using a guide track device for support and easy assembly, allowing for internal installation without altering the air inlet channel's flow cross-section and enabling maintenance from upstream, thus providing a cost-effective and aesthetically pleasing solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a separator body is internally installed to improve visual appearance and reduce space requirement, then accessibility for mounting and maintenance deteriorates

Engineering Contradiction:
Improvespace requirementVSAvoidaccessibility for mounting and maintenance
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The separating body is divided into multiple separable parts that can be individually removed through the air inlet channel opening. This segmentation allows maintenance personnel to access and remove individual components from the upstream side without requiring downstream access, thus resolving the contradiction between compact internal installation and maintenance accessibility.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a separator body is superimposed or inserted from outside to improve accessibility, then visual appearance and structural stability deteriorate

Engineering Contradiction:
Improveaccessibility for mounting and maintenanceVSAvoidspace requirement
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

Instead of accessing the separating body from downstream (traditional internal installation), the invention enables removal and installation from upstream through the air inlet channel opening. This inverted approach maintains the aesthetic benefits of internal installation while achieving the accessibility benefits of external installation.

Inventive Principle:
Principle #13The other way round (Inversion)

3Object-affected harmful factors

If the air inlet channel opening is minimized to reduce turbulence and improve visual appearance, then the ability to mount and maintain separating body deteriorates

Engineering Contradiction:
Improveturbulence and visual appearanceVSAvoidmounting and maintenance capability
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The separating body is divided into smaller separable parts that can be individually maneuvered through the minimized air inlet channel opening. This segmentation allows the complete separating body to be installed and maintained through a small opening that would be insufficient for a single large component, thus resolving the contradiction between minimized opening size and mounting capability.

Inventive Principle:
Principle #1Segmentation

AI summary

A separator system for separating drops and solid particles from an air inlet flow. The separator system includes an air inlet channel opening and a separating body which is internally installed. The separating body is arranged downstream of the air inlet channel opening so as to completely cover the air inlet channel opening and to extend flat in a mounting plane. The separating body is provided as a modular design and includes, in the mounting plane, at least one first separating part, and at least one second separating part which is arranged to be separate from the at least one first separating part.
